    Sounds interesting. I assume a good chunk is gas planning and then in water hitting ascent rates and holding stop depths? Could be a useful review.

    The most interesting part to me would be handling the slung bottle. Any discussion of slung versus pony mounted?

    For deep requirement will they accept AOW or some combo of AOW and logged dives?

    No. Advanced adventurer with (1) deep adventure dive only certifies you to 30m which is very different from the 3 dive 40m deep specialty

    Doubles would be covered by the existing Extended Range program. Per the ad this for divers not yet willing to commit to a tec rig.

    I can also see the advantage for recreational divers who don't necessarily plan to do deco but want the safety margin if they need to. My 1st deco dive was as a AOW diver trying to find a lost buddy (I hate diving 3-somes!). My only option at the time was trust my computer to figure it out.

    Sure but going beyond 30 meters on air means going beyond a recommended maximum gas density of 5.2 g/L. I wish WRSTC agencies would address that across the board. But I do accept the reality of income being prioritized over safety.

    Hmmmm. Ok so EAN40 max avoids the diver needing O2 clean gear, but the thought of the stage being for redundancy AND accelerated deco raises my eyebrow a tiny bit. Either its a bottom gas in case your primary blows out, or its a rich mix to pad or accelerate deco. If the stage has a bottom PO2 of 1.6 as a deco gas and the back gas is 1.2 or 1.4, that stage isn't going to accelerate much of anything.

    I am nitpicking though, SSI has some pretty sensible course standards generally and the XR program (aside from the deep air options, which is a personal issue of mine and thus not their problem) has robust standards. I am sure that they will have covered these aspects.

    IMHO, if you are going into deco, you are entering an overhead and thus tech diving. You should be properly trained and equipped to do so. I think this course kind of muddles the water. If you are purposely diving on a deco schedule, but considering it Rec diving, where does the line for tech diving begin and thus requiring the training?
    If equipment is the issue, that is why tech schools have gear for students to use. In my AN/DP class I didn't have a doubles wing or a second first/second stages for a twin set, much less having and entire deco tank rigging kit and there was of course other equipment that we used that the shop provided. That is what that course is there for. My trimix course was different, I had all my own gear by that point, minus tanks.
    How far into splitting hairs are we going to go? Yes technically, my dives to 60m are rec dives. I am diving for my own reasons, thus recreational.
